Welcome to the homepage for Probability (Math 4600/6600)! I will post all the homework assignments for the course on this page. Our text for the course is Ward and Gundlach, *Introduction to Probability*. During Spring 2019, the class meets twice a week at 11:00am-12:10pm TR in Boyd 323. Office hours are Tuesday** 3-5:30pm in Boyd 448.**

Probability is a deep and fascinating mathematical subject, with its own theory as well as connections to analysis, geometry, and combinatorics. In addition, it’s one of the most useful areas of applied mathematics, as entire careers and disciplines (e.g. actuarial science, quantitative finance, machine learning) rest on a firm understanding of the theory of probability. In addition, there are deep connections between probability and physics, explored in the field of statistical physics.

This is a first course in probability, which will introduce you to the basics of the subject: random variables, distribution functions, expectations, variance, conditional probability and joint distributions, independence, Bayes’ Theorem, the law of large numbers, and the central limit theorem. After this course, you’ll know most of what you need to know to pass the SOA/CAS P/1 exam (and the rest is found in chapters of the book we won’t have time to cover).

*Mathematica* will be an integral part of the course. The mathematics department has a site license for *Mathematica* and you can get a copy for your laptop or home computer free of charge. I encourage you to work through some introductory material on *Mathematica*. Some of the homework assignments and projects will require you to write *Mathematica* programs, and it’s really helpful to be able to use a computer to check your work.

## Syllabus and Policies

Please examine the course syllabus. If you think you can get by with this copy, save a tree! Don’t print it out. The course syllabus lists the various policies for the course (don’t miss the attendance policy). The course is organized by day, with the updated plan for the course visible on our shared Google Calendar. Every day, we’ll have a reading assignment before class (the book is actually very readable) and we’ll open class with a short quiz on the reading. Then we’ll have a discussion of the material in the book, followed by some in-class questions. Homework will be due on Thursdays.

## Lecture Notes

Here are links to my class notes and in-class problems for the course. The classes with computer demonstrations have Mathematica notebooks posted here.

- Lecture 1. Definitions. Outcomes, events, sample spaces. DeMorgan.
- Ward/Gundlach Chapter 2. (Note: I’m going to take this down eventually).
- Lecture 2. Axioms, Inclusion-exclusion principle.
- Ward/Gundlach Chapter 3. (Note: I’m going to take this down eventually.)

## Homework Assignments.

Starred problems are assigned for students in MATH 6600. They are extra credit problems for students in MATH 4600. (Note: Please write on your paper next to these problems which class you’re in so that we’ll be sure to grade them correctly.)

- Chapter 1. 3, 7, 9, 12*. Chapter 2. 1, 3, 4, 15, 21, 29*. Due: 1/24/2019.
